A joint effort between researchers from Hokkaido University and University of Technology Sydney has led to the development of a groundbreaking catalyst, NiOOH-Ni, showcased in a study published in Advanced Energy Materials. This innovative catalyst demonstrates a remarkable ability to enhance the efficiency of ammonia conversion, offering promising advancements in wastewater treatment, green chemical production, and hydrogen generation. By combining nickel with nickel oxyhydroxide, the catalyst presents a new avenue for addressing environmental challenges associated with ammonia pollution. The catalyst's electrochemical process allows for the formation of nickel oxyhydroxide particles on porous nickel foam, significantly boosting ammonia conversion efficiency. Professor Zhenguo Huang from the University of Technology Sydney highlights NiOOH-Ni's superior performance compared to traditional catalysts and its adaptability to produce nitrite or nitrate based on voltage levels, enabling diverse applications in wastewater treatment and clean energy production. Associate Professor Andrey Lyalin from Hokkaido University underscores the durability and cost-effectiveness of NiOOH-Ni, positioning it as a viable alternative to expensive catalysts like platinum commonly used in industrial processes. The catalyst's long-term stability and reusability make it a game-changer for large-scale applications, potentially revolutionizing the industrial landscape by offering a sustainable solution for wastewater treatment and clean energy production. Funded by institutions such as the Australian Research Council and the Japanese Ministry of Education, Culture, Sports, Science and Technology, this collaborative research exemplifies the global effort to drive innovation and address pressing environmental and energy challenges. The development of NiOOH-Ni opens up new possibilities for sustainable technologies and underscores the importance of catalytic advancements in shaping a greener future.
